[Strategia_In_Ultima]

Woe oh woe, SEIV will no longer play! It has been like this for some time, but just now I remembered it might have something to do with the SEIV folder being read-only, so I went to the Administrator account (which I mainly use for installing and modding, and sometimes for playing games that won't work without Administrator(!) privileges - I'm looking at you, Black&White, Age of Mythology, Dungeon Siege!!) and lo and behold, there was a green square in the Read-Only box in the SEIV folder properties!!!z0mg! Now while I am aware of the little box's existence next to the tick mark, I haven't a clue as to what it is used for, but that aside I clicked the checkbox and it turned white as it should. I then went on to play, and SEIV pulled the same trick on me as it has done for some time; Invalid File Error at the end of a turn, after which it wouldn't respond to anything save for a Ctrl+Alt+Delete forced process termination. I tried again, same results. I went to the folder, and what did I find? The darned box again! I cleared it and clicked OK, then to be sure I clicked Properties again. It was bloody there! Apart from my acute unreasonable hatred of anything with four like-sided sides, I have absolutely no idea of what to do with regard to the game. Can anyone please help?
